Prosafe M4100-50G-POE+ failed after update

I had a firmware updates fail when upgrading several units when going from 10.0.1.16 to 10.0.2.26.  Exact boot console conditions as previously stated.  Switch was effectively dead as it rebooted itself.   I made the mistake of trying image1 and image2... that's when I lost functionality of the switch completely.   I noted on other units where the firmware upgrade failed, that image1 I regularly tried to upgrade was blank or gone when the switch rebooted on it's own after an attempt.  (checked this in Maintenance, File Management...Dual Image Configuration) The image2 was the only one allowing the switch to boot up... until I wiped it out too during an attempt to try flashing image2.   Looked all over for a recovery process and was able to get to a CFE prompt with Ctrl-C and not much else.   Not able to access the typical recovery options.  I submitted an RMA for a replacement, that won't get here till Monday(being Friday).   Since I had the unit yet, I decided to see what I could do in the CFE arena.  Did find a number of sample interactions in the CFE CLI, none for the netgear switch itself, but did get enough incite to remedy the situation.   Supprised Netgear doesn't post the recovery procedure for a semi-bricked unit that is in this state.  It wasn't too difficult.   Now I don't need the RMA'd replacement unit anymore.

Basic steps were to get into CFE... easy enough... reactivate eth0 with the -auto switch manually  so the switch could see my network for tftp... used the flash command to overwrite the flash2.stk1 image via tftp.   It rebooted and all was good again.
